Question

The elevation of an underwater cave is -120 feet relative to sea level. A submarine descends to the cave. the submarine rate of change in elevation is no greater than -12 ft per sec. how long will it take to reach the cave

Answer 1

Answer:

Time taken by the submarine to reach the cave is 10 seconds.

Step-by-step explanation:

We are given that,

The elevation of the underwater cave = -120 feet.

The rate at which the submarine descends to the cave = -12 feet per second

Thus, we have,

The time taken by the submarine to reach the cave = $\frac{-120}{-12}$ = 10 seconds.

Hence, the time taken by the submarine to reach the cave is 10 seconds.
